How to Use Video Frame Size Calculator

The Video Frame Size Calculator helps video engineers, developers, and media professionals estimate raw data requirements for any video configuration.

  1. Enter Width and Height — Input the video resolution in pixels (e.g., 1920 × 1080 for Full HD or 3840 × 2160 for 4K).
  2. Select Pixel Format — Choose the colour space and bit depth that matches your workflow. The Video Frame Size Calculator supports YUV 4:2:0, YUV 4:2:2, YUV 4:4:4, RGB 24-bit, RGBA 32-bit, and HDR 48-bit.
  3. Enter Frame Rate — Type the frames per second (e.g., 24, 30, 60, or 120 fps).
  4. Enter Duration — Input the video duration in seconds. The Video Frame Size Calculator will compute total frame count and overall data volume.
  5. Read the Results — Instantly see pixels per frame, per-frame data size, raw bitrate, and total uncompressed data for the full clip.

Formula & Theory — Video Frame Size Calculator

The Video Frame Size Calculator applies the following chain of formulas:

Pixels per Frame        = Width × Height
Bits per Frame          = Width × Height × Bits per Pixel
Bytes per Frame         = Bits per Frame ÷ 8
Raw Bitrate             = Bytes per Frame × Frame Rate × 8    (bits/second)
Total Frames            = Frame Rate × Duration (seconds)
Total Uncompressed Data = Bytes per Frame × Total Frames
Symbol Meaning
Width Frame width in pixels
Height Frame height in pixels
Bits per Pixel Colour depth determined by pixel format (e.g., 12 for YUV 4:2:0)
Frame Rate Frames captured or displayed per second (fps)
Duration Length of the video clip in seconds

Common Pixel Formats and Their Bit Depths

Format Bits per Pixel Typical Use
YUV 4:2:0 12 H.264, H.265, streaming
YUV 4:2:2 16 Broadcast, professional cameras
YUV 4:4:4 24 High-quality grading, lossless
RGB 24-bit 24 Image sequences, raw workflows
RGBA 32-bit 32 Graphics with transparency
RGB 48-bit HDR 48 High dynamic range production

The Video Frame Size Calculator uses these values directly to give you accurate uncompressed data estimates.

Use Cases for Video Frame Size Calculator

The Video Frame Size Calculator is an essential tool in many production and engineering scenarios:

  • Storage planning — Before a shoot or render, use the Video Frame Size Calculator to estimate how many terabytes of storage you will need for raw or lossless footage at a given resolution and frame rate.
  • Codec parameter selection — Compare uncompressed data volumes across different resolutions to decide whether H.264, H.265, or AV1 will achieve an acceptable compressed bitrate for your target file size.
  • Streaming bandwidth estimation — Understand the theoretical maximum bitrate needed before applying codec compression, which helps set realistic encoding targets for live or VOD streaming.
  • Image processing pipelines — Developers building frame-by-frame video analysis tools can use the Video Frame Size Calculator to allocate memory buffers and plan I/O throughput for processing uncompressed frame data.
  • Camera and recording system selection — Evaluate whether a recording device's internal storage or external SSD can sustain the data rate required for a specific resolution, frame rate, and pixel format.
  • Educational and research use — Understand the data demands of raw video and how compression codecs achieve their efficiency gains relative to the baseline computed by the Video Frame Size Calculator.

Frequently asked questions about Video Frame Size Calculator

What does the Video Frame Size Calculator compute?

The Video Frame Size Calculator outputs pixels per frame, the uncompressed size of a single frame, the raw uncompressed bitrate (data per second), total frame count, and the total uncompressed data volume for your specified duration.

Why is the total size so much larger than actual video files?

The Video Frame Size Calculator shows raw, uncompressed data. Modern video codecs such as H.264, H.265, and AV1 use temporal and spatial compression to reduce file size by 10–100x compared to uncompressed data.

What pixel format should I choose?

YUV 4:2:0 at 12 bpp is the most common format used in H.264 and H.265 encoding. Choose YUV 4:2:2 for broadcast production or RGB 24-bit for raw image sequences and lossless workflows.

How is raw bitrate calculated?

The Video Frame Size Calculator multiplies the uncompressed bytes per frame by the frame rate: Bitrate = Width × Height × Bits Per Pixel × Frame Rate. This gives the theoretical bandwidth needed to stream or store uncompressed video.
